Google tells me that Android, ChromeOS, and OpenMandriva use LLVM. That's pretty thin. This is all rather problematic and it isn't clear (to me) how to proceed at this time. Do we have any projections on when all this will be fixed up? > The series is based on mm-new. I actually carry kexec patches in the mm-nonmm-[un]stable branches. But the series applies OK anyway.
